Disclosed is a parameter setting method, device and multi-rotor drone. The method for a multi-rotor drone includes: acquiring identity information of all the ESCs; parsing parameter information of the ESCs according to the identity information, where the parameter information includes a common control parameter domain parameter and an independent control parameter domain parameter; acquiring the parameter information modified by the user; updating the common control parameter domain parameters of all the ESCs based on the modified common control parameter domain parameter; and updating the independent control parameter domain parameter of the target ESC based on the modified independent control parameter domain parameter. According to the method, the parameter information includes the common control parameter domain parameters and the independent control parameter domain parameters, and parameters are updated in different ways, thereby ensuring coordinated system-wide operations, and ensuring accuracy of parameter update.

Parameter setting method, device and multi-rotor drone

An operation control method and system for a clothing treatment device having a drum and a motor is provided. Load inertia of the drum and a fluctuation parameter of the motor are obtained. Load eccentric mass of the clothing treatment device is obtained based on the load inertia, the fluctuation parameter, and predetermined relationship data that is obtained based on pre-stored load inertia, torque fluctuation and load eccentric mass. The fluctuation parameter can be a torque fluctuation parameter or a rotation speed fluctuation parameter. The clothing treatment device can be controlled according to the load eccentric mass to optimize washing operations. For example, clothing and/or inlet water amount can be timely adjusted according to the calculated load eccentric mass. Thus, the clothing treatment device is prevented from producing significant noise during operations, and the service life of the clothing treatment device can be prolonged.

Operation control method and system for clothing treatment device, clothing treatment device, and storage medium

A drum washing machine, and a control method and a control apparatus for same are provided. The control method for the drum washing machine comprises the following steps: acquiring an average starting power of a drum in a starting process of the drum; acquiring a load range to which a current load of the drum belongs according to the average starting power; and setting a weighing protection velocity fluctuation threshold according to the load range to which the current load of the drum belongs. A value of the current load is obtained by using a correspondence between load with different weights and average starting powers. A weighing protection velocity fluctuation threshold is set according to the value of the current load to avoid the collision with the drum and non-dehydration in case of only one piece of clothing.

The present disclosure provides a preparation method of an optical fiber device having a polymer micronano structure integrated in an optical fiber, the method comprising: welding a hollow optical fiber so that the hollow optical fiber is welded between two solid optical fibers, ablating the welded hollow optical fiber utilizing a femtosecond laser ablation technology so that a channel vertical to an inner wall is ablated on the hollow optical fiber, filling a colorless and transparent liquid photoresist material inside the hollow optical fiber which has been ablated so that the inside of the hollow optical fiber is filled with the photoresist material, and polymerizing on the photoresist material inside the hollow optical fiber utilizing a femtosecond laser two-photon polymerization technology.

Optical fiber device having polymer micronano structure integrated in optical fiber and preparation method thereof

The present disclosure relates to a front-loading washing machine and an unbalance detection method and device thereof. The method comprises: when a drum operates at a low constant speed, detecting the torque of the drum and acquiring average torque values; when the roller operates at a constant acceleration speed, acquiring average torque values and a minimum value of the average torque values of the drum in real time; determining whether a difference between the average torque and the minimum value of the average torque values is greater than a preset unbalance threshold; and if so, determining that dynamic unbalance occurs on the drum; otherwise determining that no dynamic unbalance occurs on the drum. Because no sensor is needed for unbalance detection, cost and the detection difficulty are lowered, and damages to mechanical components due to collisions caused by dynamic unbalance when the drum operates at a high speed is avoided.
